Hey, I admittedly forgot and left out some information on accident. First, I'm not entirely sure whether it's 10 GB, but I checked and I think you're right, Bibilit.
Rsolberg, I actually installed the firmware update a few months ago and forgot about it. I tried again and it notified me that it was up to date.
The thing I forgot to mention is that I think the PRAM battery might be dead, since the date and time reset every time I restart the computer. Would this happen to have anything to do with the issue?
